Abstract :
The confidentiality of data is one of the most important issues in cloud storage system. We address the privacy issue of decentralized cloud storage system using threshold cryptography. The major challenge of designing this cloud storage system is to provide a better privacy guarantee. To achieve this goal, we propose a threshold encryption scheme and integrate it with a secure decentralized erasure code to form a secure cloud storage system, where the user generates a secret parameter participated in system encryption and decryption of plaintext blocks in the combine process. Our cloud storage system meets the requirements of data robustness and confidentiality.
